Sigh... That's what happens when you're overtired and working at 3 or 4 in the morning...

spinbutton1.Xalign = 1.0f;

You can't set it in Stetic. You have to do it in code. And you actually have to call the method that you put the call in before it can run... Amazing how getting up and getting some coffee in you can "debug" an application...
